Disabling security software can sometimes resolve Microsoft Office apps not opening issue due to the potential conflicts between the security software and the Office applications. Security software, such as antivirus or firewall programs, are designed to protect your computer from threats, including malware, viruses, and unauthorized access.

However, these programs can occasionally be overzealous in their protective measures and may mistakenly identify legitimate software, like Microsoft Office apps, as potential threats.

When this happens, the security software might block or restrict access to certain features or functions of the Office applications, preventing them from opening or functioning correctly. This is known as a false positive, and it can be a source of frustration for users who are unable to use their Office apps due to interference from their security software.

Users reported that disabling Avast, AVG, and similar antivirus apps helped them to resolve the problem. Alternatively, you can update your antivirus to the latest version, add Office to the exclusion list, or contact your antivirus vendor for support.
